What is Periodicity?

Periodicity refers to the repeating pattern of properties of elements in the periodic table.

100

What are alkaline earth metals?

These metals are highly reactive and tend to form 2+ cations with non-metals.

100

What is the element in Group 17 is commonly used to disinfect water?

Chlorine

100

What is the chemical formula for dinitrogen pentoxide?

N2O5

100

Duck feathers are said to be this, allowing them to swim under water briefly.

Hydrophobic

200

What is ionization energy?

Ionization energy is the energy required to remove an electron from a neutral atom in its gaseous state.

200

What is the element with the highest melting point in Group 2?

Beryllium

200

What is the most reactive Halogen?

Fluorine

200

Why does Nitrogen gas in the atmosphere tend to be inert?

Due to its strong triple bond

200

Duck eggs are generally white. However, some eggs can be this color.

Pale green

300

What is the trend of atomic radius within a period?

The atomic radius generally decreases from left to right within a period on the periodic table.

300

What is the element with the lowest electronegativity in Group 2?

ammonium nitrate is considered a good fertilizer. Why would this be true?

Hint: Consider what the molecular formula is and how it would separate into ions.

It can dissociate to form NH3 and HNO3. Two sources of nitrogen. Nitrogen is good for plants helping form amino acids.

500

Ammonium ions are said to contain a dative or coordinate bond. What is meant by this type of bond.

Hint: Consider the structure of ammonia and the ammonium ion

A bond formed from one atom providing both electrons needed to create the bond.
